Have you tested that the resulting kernels work on the relevant hardware? The old drivers may be crufty but they presumably have been tested by people and at least somewhat work. So I'd be inclined to leave the defconfigs alone until someone can test that the new driver works at all. I gave it a quick spin on a G5 I have access to and dmesg has a bunch of errors in it (see below). I can't actually tell if the display is working because the machine is remote, and I can't go and check it at the moment because the office is closed. cheers [ 128.563251] nouveau 0000:f0:10.0: NVIDIA NV34 (034900b1) [ 128.565720] nouveau 0000:f0:10.0: bios: version 04.34.20.18.00 [ 128.570994] nouveau 0000:f0:10.0: bios: OOB 1 00000cdd 00000cdd [ 128.571702] nouveau 0000:f0:10.0: bios: OOB 1 00000ce1 00000ce1 [ 128.571723] nouveau 0000:f0:10.0: bios: OOB 1 00000cde 00000cde [ 128.571731] nouveau 0000:f0:10.0: bios: OOB 1 00000cdf 00000cdf [ 128.572438] nouveau 0000:f0:10.0: bios: OOB 1 00000ce5 00000ce5 [ 128.572459] nouveau 0000:f0:10.0: bios: OOB 1 00000ce2 00000ce2 [ 128.572468] nouveau 0000:f0:10.0: bios: OOB 1 00000ce3 00000ce3 [ 128.579187] nouveau 0000:f0:10.0: bios: OOB 1 00000ce9 00000ce9 [ 128.579210] nouveau 0000:f0:10.0: bios: OOB 1 00000ce6 00000ce6 [ 128.579219] nouveau 0000:f0:10.0: bios: OOB 1 00000ce7 00000ce7 [ 128.580230] nouveau 0000:f0:10.0: bios: OOB 1 00000ced 00000ced [ 128.580252] nouveau 0000:f0:10.0: bios: OOB 1 00000cea 00000cea [ 128.580261] nouveau 0000:f0:10.0: bios: OOB 1 00000ceb 00000ceb [ 128.581543] nouveau 0000:f0:10.0: bios: OOB 1 00000cf1 00000cf1 [ 128.581567] nouveau 0000:f0:10.0: bios: OOB 1 00000cee 00000cee [ 128.581576] nouveau 0000:f0:10.0: bios: OOB 1 00000cef 00000cef [ 128.582456] nouveau 0000:f0:10.0: bios: OOB 1 00000cf5 00000cf5 [ 128.582479] nouveau 0000:f0:10.0: bios: OOB 1 00000cf2 00000cf2 [ 128.582487] nouveau 0000:f0:10.0: bios: OOB 1 00000cf3 00000cf3 [ 128.583314] nouveau 0000:f0:10.0: bios: OOB 1 00000cf9 00000cf9 [ 128.583336] nouveau 0000:f0:10.0: bios: OOB 1 00000cf6 00000cf6 [ 128.583344] nouveau 0000:f0:10.0: bios: OOB 1 00000cf7 00000cf7 [ 128.584186] nouveau 0000:f0:10.0: bios: OOB 1 00000cfd 00000cfd [ 128.584208] nouveau 0000:f0:10.0: bios: OOB 1 00000cfa 00000cfa [ 128.584217] nouveau 0000:f0:10.0: bios: OOB 1 00000cfb 00000cfb [ 128.585635] nouveau 0000:f0:10.0: bios: OOB 1 00000d01 00000d01 [ 128.585658] nouveau 0000:f0:10.0: bios: OOB 1 00000cfe 00000cfe [ 128.585666] nouveau 0000:f0:10.0: bios: OOB 1 00000cff 00000cff [ 128.589405] nouveau 0000:f0:10.0: bios: OOB 1 00000d05 00000d05 [ 128.589428] nouveau 0000:f0:10.0: bios: OOB 1 00000d02 00000d02 [ 128.589436] nouveau 0000:f0:10.0: bios: OOB 1 00000d03 00000d03 [ 128.590316] nouveau 0000:f0:10.0: bios: OOB 1 00000d09 00000d09 [ 128.590338] nouveau 0000:f0:10.0: bios: OOB 1 00000d06 00000d06 [ 128.590346] nouveau 0000:f0:10.0: bios: OOB 1 00000d07 00000d07 [ 128.591173] nouveau 0000:f0:10.0: bios: OOB 1 00000d0d 00000d0d [ 128.591196] nouveau 0000:f0:10.0: bios: OOB 1 00000d0a 00000d0a [ 128.591205] nouveau 0000:f0:10.0: bios: OOB 1 00000d0b 00000d0b [ 128.593513] nouveau 0000:f0:10.0: tmr: unknown input clock freq [ 128.595886] nouveau 0000:f0:10.0: fb: 64 MiB DDR1 [ 128.609034] [TTM] Zone kernel: Available graphics memory: 500010 KiB [ 128.609058] [TTM] Initializing pool allocator [ 128.609106] nouveau 0000:f0:10.0: DRM: VRAM: 63 MiB [ 128.609115] nouveau 0000:f0:10.0: DRM: GART: 128 MiB [ 128.609134] nouveau 0000:f0:10.0: DRM: BMP version 5.38 [ 128.609144] nouveau 0000:f0:10.0: DRM: DCB version 2.2 [ 128.609155] nouveau 0000:f0:10.0: DRM: DCB outp 00: 01000122 00000004 [ 128.609168] nouveau 0000:f0:10.0: DRM: DCB outp 01: 02010200 11b088b8 [ 128.609177] nouveau 0000:f0:10.0: DRM: DCB outp 02: 02010201 11b00703 [ 128.609222] nouveau 0000:f0:10.0: DRM: Loading NV17 power sequencing microcode [ 128.610947] nouveau 0000:f0:10.0: DRM: MM: using M2MF for buffer copies [ 128.613371] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

That was a problem for the G5s. There were other issues for more ancient machines with older nVidia GPUs. Additionally a lot of those Apple machines don't have a BIOS ROM to get the various tables from. At this stage unfortunately I don't have access to most of that HW to test with anymore. I do have one G5 I might be able to dig out of my basement this week to try out. In any case, digging out that patch should be useful as powerpc64 is still 64k pages :) Cheers, Ben.

I think nouveau has code to find these in nvkm/subdev/bios/shadowof.c, so at least that should have been working, but maybe some debugging/instrumentation would be useful there. > Genuine concern or noise?

I've just noticed that v1 (patch #1/1) & v2 (patch #1/2) lack Cc: to powerpc Maintainers so they cannot see the context of changes in this patch. Also you've proposed v1 yourself and it has already contained modifications to defconfigs (removal of setting the config options for the old drivers) in addition to marking the old drivers as BROKEN. It now turns out that v1 has also never been tested. :( Please don't submit untested patches without marking them as such. >> The old drivers may be crufty but they presumably have been tested by >> people and at least somewhat work. >> >> So I'd be inclined to leave the defconfigs alone until someone can test >> that the new driver works at all. @Michael: Fully agreed.
